When I navigate to any of the drawings that are linked to from my presentation, the window that is used to display the document seems to be of arbitrary size.

I've tried a number of options and no one seems to like the "Open in Full Screen" option. So, I've got them set to open to "Fit Page." This works pretty well, but if I could get Acrobat to always open Maximized, then it would be perfect. I can't seem to find a setting for that. Instead they open at mixed sizes and I have to click the Maximize button to be able to see any drawing detail onscreen.

The only suggestion I can offer as I also cannot get this to work is to use something like the free MW snap (MW Snap) to capture and save your drawings as pictures and the put them into a slide as a full page image and navigate to and from that instead of the PDF.
